. CARTER, OF CHICAGO, ILLINOIS DRAW WORKS Application led March 24, 1928. Serial No. 264,424.

This invention relates to draw works for use in connection with the drilling of wells, and has for its object to provide a new and improved device of this description.

5, The invention has as a further object to provide a draw works which is simple in construction and strong and rigid when in operation.

The invention has as a further object to provide a draw works that can be easily, quickly and elfectively assembled at the point of use.

The invention has further objects which are more particularly pointed out in the accompanying drawings.

Referring now to the drawings, Fig. l is a View showing one form of device einbodyng the invention.

Lilie numerals refer to like parts throughout the several figures.

Referring now to the drawings, I have shown in Fig. lone form of draw works having a series of metal shaft supports l, each having the shaft bearing elements 2 and 3 integral therewith. Mounted in these bear-- ing elements arethe shafts 4 and 5. (lo-op erating with the bearing element 2 is the removable hearing element or cap 5 connected in operative position by the bolts 6. Co-

operating with the bearing element 3 is the removable bearing element or cap 7 held in position by the bolts 8. The bearing elements are provided with bushings for the shafts, the bushings being divided into sections 9 and i0. 'The bushings are provided with means for preventing them from being displaced lateraily but which permit them to be moved circumferentially of the shaft.

In the construction herein shown, this result is secured by means of the annular projection ll on the bushing section 9 which lits into an annular groove ilo in the top bearing member and the annular projection l2 which fits into the annular ,o toove in the lower bearing section. rille two annular projections on the bushing sections are different sizes so that when the bushing sections are in position, tney cannot rotate with the shaft.

llfhen it is desired to insert the bushings, it is only necessary to remove the upper bearing element or cap, as shown in l0 and place the annular projections ll and l2 in proper position with relation to the respective grooves lla. and 12e, and then rotate the bushing sections circumfer-entially of the shaft so as to bring them into proper position. To remove the bushing sections, it is only necessary to remove the upper bearing section an d rotate he bushing sections until they are disconnected 'from their bearing sections.

ln order to insure the proper lubrication of the shafts. the bearing sec ions and 7 are provided wit i oil. reservoirs i3 and 14. Oil is inserted in the oil reservoir by means of an oil passageway l5 through the support l and the bearing members 3 and 7, the oil passageway open support l.

rfi-.n oil passageway i? lea-ds from the reservoir i4 through the hearing member and the bushing to the shaft, (see Fig. 2). Since the bushings cannot rotate with the shaft, this insures oil being supplied to the bearings when there is oil in the oil` reservoirs. The oil reservoir 14 is provided at the bottom with an opening normally closed by the removable plug i8. By moving the plug, the reservoir may be cleaned out. The oil reservoir 13 also is provided at its bottom with an in; 1G on the front of the opening closed by a removable plug 20. Oil is inserted in this oil reservoir through this opening by removing the plug 2O and using a forcing device of some kind.

It will be seen that by means of this construction, the oil passageway 15, the bearings for both shafts may be oiled from the platform side of the draw works. T he bearing supports 1 are connected together by an aligning member 21 at! the top and an aligning member 22 at the bottom. yll`he support-- ing member 1 and the aligning member 22 are provided with interlocking parts. ln the construction shown, the supporting member 1 is provided with a projection 23 which fits in between the projections 24 on the aligning member. kThe projection 23 is planed off Vand the face of the aligning member between the` projections 24 is planed off `or finished so that when the two faces are brought together,y the shaft bearings and shafts will be properly aligned.y The ends of the projections 24 and the parts of the support 1 which they engage may also be planed or finished `so as'to have the proper relation with each other. lt will be seen that either set of surfaces when properly finished will produce the aligning effect.

Some means is provided for properly connecting the interlocking parts 23 and 24. ln the construction shown this is produced by a removable connecting member 25 which passes through openings in the interlocking members and which is preferably provided f with an inclined face 26 which engages a similarly inclined face on one of the inter locking members so as to insure the finished aligning faces of the aligningvmember and thesupports to be brought into proper aligning position. rlher removable connecting piece is held in place byY a suitable'fastening device which is shown as a bolt 27. The bottom "aligning member 22 and the supports 1 are also provided with interlocking parts. rlhe posts are provided with the projections 28 which fit `in between the projections 29 on the aligning member. The faces of the aligning membei between the projections and the ends of the projections 2S are properly nished in the shop so that when they are broughtvintocontact'the shafts and bearings will be properly aligned. rl`he aligning mem- Aber 22 and the supports 1f are connected together by similar removable connecting pieces 25 similar to those used in connection with the aligning member 21. lt will be seen that when the supports land the aligning members 21 and 22 are properly connected and 31 by means of bolts or the like 32 and 33 which also pass through the supports 1. There are also bolts 34 connecting the aligning member 21 with the cross member 30 which bolts pass through elongated slots 35 so as to secure proper adjustment of the parts. The bottom aligning member is provided with a strengthening rib 36, and is fastened to the cross member 31 by the bolts 38. The-bolts 38 preferably pass through V openings 39 in the ribs 36. T he bottom aligning member is preferably provided with a positioning mark 39a which is placed opposite a positioningmark on the cross member 31 of the platform 40 Vso as to insure the proper location of the member with relation to the platform. This aligning member is also preferably provided with holes 41 for spikes or other fastening devices so as to hold it in proper position while the other parts are being assembled so that after assembly the shafts and parts thereon will be properly lo-A cated with respect to the vises with which they co-operate. Any ofthe bearingsupporting members may be rocked about the lower shaft Y4 so as to bring the bearing 3 into proper position where it may be inspect-ed from the platform 40l by removing the bearing member 7 and the fastening devices 32 and 33 and the wedge connectingpieces 25.

l have shown the shafts 4 and as being provided with the usual parts of the draw works. rl`he aligning faces of the supports V1 and the aligning devices 21 and 22 are properly finished so that when the parts are brought together, the bearings of the shafts will be in proper alignment. .it will thus be seen that whenever the device is set up outfin the field, and Vthesevaligning surfaces brought in proper relation, the bearings of the shafts will always be in alignment. rlf'he device may, I therefore, be taken down and movedl whenever and wherever desired, and when again set up, alignment of the bearings isI assured. rThe bearingsupporting members 1 are preferably enlarged at the top and bottom and `at the points where the bearings are located and are reduced in size at intermediate points,.as clearly shown in Figs. 1 and 3. The bearing members 2 and 3 are preferably provided with strengthening webs 2a.
